Top SchoolRafael Lucio is a seasoned software leader and founder based in São Paulo with over a decade of experience building front-end and platform-level systems, and more than 14 years of continuous growth from hands-on developer to Principal and Staff Engineer roles. He has led architecture, refactoring and technical-debt prioritization at scale—shaping cross-team solutions and influencing product-technical tradeoffs during his long tenure at Creditas and as Tech Lead at Easynvest. Rafael combines deep front-end expertise (early roles at Tesla Brazil and legal/finance firms) with senior platform thinking, mentoring engineers to adopt critical perspectives and reusable solutions. Recently he transitioned to founding Cosmicraft Technologies while holding a brief Staff Engineer stint at Sanctu, signaling a move toward entrepreneurship without leaving technical craft behind. His background spans formal CS education, an MBA in Java/SOA/IoT, and a Full-Stack certification, reflecting both practical delivery and continuous learning. A pragmatic architect who still ships code, he brings a rare mix of product sensibility, people leadership and hands-on implementation.
